The prefs.js file stores customized settings, so it's difficult to know why Malwarebytes is suddenly upset about it. Does Malwarebytes give any specific information about what it doesn't like in the file?

Also, don't remove prefs.js while Firefox is still running.

If you let Malwarebytes remove prefs.js while Firefox is closed, at the next startup, your settings should be back to default (e.g., built-in home page, no new tab page pinned tiles, original preferences values, etc.), but you will still have your saved bookmarks, passwords, and add-ons.

Hi,

To answer your question, MB's report said this:

"File: 2 Trojan.Agent.CK, C:\WINDOWS\SYSTEM32\TASKS\OINSTALL, Quarantined, [4440], [400551],1.0.8153 PUP.Optional.Conduit, C:\USERS\Z\APPDATA\ROAMING\MOZILLA\FIREFOX\PROFILES\O182YAT8.NEW\PREFS.JS, Replaced, [215], [301520],1.0.8153"

What do you think?

... PUP.Optional.Conduit ...

Conduit is associated with numerous "potentially unwanted programs" (PUPs), including some browser extensions. I'm not sure which extensions you have installed, but it's worth reviewing.

You can view, disable, and often remove unwanted or unknown extensions on the Add-ons page. Either:

• Ctrl+Shift+a (Mac: Command+Shift+a)
• "3-bar" menu button (or Tools menu) > Add-ons
• type or paste about:addons in the address bar and press Enter/Return

In the left column of the Add-ons page, click Extensions.

Then cast a critical eye over the list on the right side. Any extensions Firefox installs for built-in features are hidden from this page, so everything listed here is your choice (and your responsibility) to manage. Anything suspicious or that you just do not remember installing or why? If in doubt, disable (or remove).

Any improvement?

Hi,

I looked over the extensions and I dont really suspect any that stand out as hazardous. Check out my list of addons and let me know what you think. Thank you:

I've heard of Stylus and uBlock Origin.

Just Disable them and see what happens.

No, those are the ones I have heard of. Meaning those should be fine. The others are the ones I don't know anything about.

I ran this question on the malware forum. Someone said I should reinstall firrefox which is what I'm doing now.

Btw, would you please answer my thread here: https://support.mozilla.org/en-US/questions/1243139

Could you paste here the content of this prefs.js file?

I never connected Thunderbird to a Gmail account, so I have no idea.
